VENTILATOR.

SPECIFICATION forming part of Letters Patent No. 495,141, dated April11, 189R.

Application filed October 14, 1891. Serial No. 408,660- (No model.)

To all whom it may concern.-

Be it known that I, CLARK H. NORTON, of Syracuse, in the county ofOnondaga, in the State of New York, have invented new and usefulImprovements in Ventilators, of which the following, taken in connectionwith the accompanying drawings, is a full, clear, and exact description.

My invention relates to improvements in ventilators, and has for itsobject the production of a simple and effective device which isparticularly simple, strong, durable and economical in manufacture.

To this end the invention consists, essentially, in a hood adapted toreceive the heated air and gases, a pipe communicating with the hood forconducting the heated air and gases therefrom, a branch pipe leadingfrom the former pipe for conducting the air and gases in anotherdirection, an inner sleeve at the union of said pipes, and a dampermovably mounted at theunion of said pipes and adapted to makecontactwith said inner sleeve for varying the direction of the heatedair and gases.

The invention furthermore consists in a pipe consisting of two sections,one telescoping within the other, a collar on the lower section or hoodnipple, a collar on the hood removably secured to the former collar, aguide on the upper section of pipe, and a rod having one extremitysecured to the hood and the other movable in said guide; and in thedetail construction and arrangement of the parts, all as hereinaftermore particularly described and pointed out in the claims.

In describing this invention, reference is had to the accompanyingdrawings, forming a part of this specification, in which, like lettersindicate corresponding parts in all the views.

Figure 1 is an isometric perspective, representing a section of an upperand lower floor, an upright partition, a portion of a chimney, a range,and my ventilator operatively mounted above the range and connected tothe chimney independent of the pipe. Fig. 2 is a vertical sectional Viewof the upper portion of the hood and the ventilator pipe communicatingtherewith. Fig. 3 is an isometric perspective of the detached collarsadapted to be secured to the hood and to the lower section of theventilator pipe. Fig. 4 is a face view of a damper movably mounted inthe pipe of my ventilator, and Fig. 5 is a transverse horizontalsectional view, taken" on line 55 Fig. 4.

In many ventilators, asheretofore constructed, more or less difficultyis experienced from the fact that the ventilator pipe does not open intothe chimney independent of the stove pipe, but usually dischargesdirectly into the stove pipe. V

Another source of ineffectiveness in many ventilators is the lack of asimple and effective damper for governing the direction of which theheated air and gases are passed, and in the use of a-hood, which, whenin close proximity to the stove or range is unsup ported from lateralmovement, and is thus liable to become swayed a suificient distance tobend the nipple or short section of pipe secured to the hood and preventthe same from telescoping within the upper section.

In my invention the ventilator pipe is entirely independent of theordinary stove pipe, a simple construction of damper and internal sleeveregulates the flow within the ventilator pipe, lateral movement of thehood is entirely obviated at any elevation, and the component partsthereof are so simple and strong as to greatly increase the'durabilityjof'the ventilator. v

A represents any suitable chimney provided with a central flue or outletpassage; B- any suitable construction of stove or range, and O a stovepipe connected to the stove and to the chimney for conducting theproducts of combustion into thechimney.

D- is the ventilator pipe consisting of the upper and lower telescopicsections -dd, the lower one forming an upwardly extending nipple on thehood F.

-E is a branch pipe communicating with the upper extremity of the pipe Dand piercing the chimney at a point at one side of the upper end of thestove pipe O and preferably at a point somewhat elevated above said endof the pipe -C and discharging into the outlet passage of the chimney.The hood F is adapted to be moved in close proximity to the stove orrange and to conduct the heated air or gases into the pipe It is wellknown that although the chimney of a house is used constantly, the stoveis frequently changed as the life of a stove is but limited.Consequently, I secure the hood to the thimble -d reinovably in orderthat if the small hood suitable for an ordinary stove has been in use,and it is desired to replace the same with a hood suitable for a range,the old hood may be readily detached and a new one instantly secured inposition at a minimum expense. Any suitable means for securing the hoodto the pipe section d may be used.

At Figs. 1, 2 and 3 I have shown a collar formed of cast metal or othersuitable material rigidly secured to the hood by screws f and providedwith movable projections f having one or more laterally extending armsAt the lower extremity of the pipe section dis a collar d ha.v

, ing slot-s d 'of greater length than width whereby when the arms f ofthe projections are in line with said slots, the same may be readilyforced to the upper face of the flange d -upon said collar, and the hoodfirmly held in position by a quarter turn of the projections G- is apulley or round bearing mounted within the pipe section d upon the ping-, and H a flexible chain secured at -h to the upper end of the pipecZ- telescoping within the section d and having its opposite extremitypassed over the pulley G-and secu red to a counterbalance G' for thehood F- and its projecting thimble or pipe section d.

It will readily be understood that with the utmost ease, a comparativelyweak person may readily elevate the hood to the required plane and thendepress the same in position over the stove to receive the heated airradiating from the stove, or the gases produced by cooking or otherhousehold industry.

It is evident that the hood must have considerable movement in order toaccommodate the various household utensils, and that for the sake ofeconomy, the least possible amount of pipe -D- must be usedConsequently, when the hood is in a low down posit-ion, and isunsupported by the top of the stove or range, there is great liabilityof the hood being unduly swayed laterally and the pipe sections beingthereby bent or injured, whereupon an easy telescopic movement of thesections -cld' is rendered impossible. To entirely obviate thisundesirable result, I provide a stiff rod I having one end firmlysecured to the flange d of the collar d and the other movable in theguide or eye iprovided on a collar t"- mounted upon the pipe section d.As the hood is raised, the rod .I slides through the eye or guide t' andwhen the desired adjustment of the hood is reached, a suitable clamp t'movable in the eye or guide z'-, bears against the rod --I, andeffectually holds the hood in its adjusted position. On the other hand,the rod slides equally easy when the hood is depressed, and the clamp 7?may then be operated to retain the hood as before.

J- represents the damper movably mounted at the point of union of thebranch pipe E and the pipe section --cl-, and j is an inner sleeve alsosecured at said point of union and so formed that one extremity j of itstop edge projects above the other extremity j This lower extremity jprojects, however, just above the incline e at the lower peripheral edgeof the inner end of the pipe E, or more strictly speaking, a nippleformed upon the pipe D- and adapted to receive the end of the, pipe E.

The damper J- consists of a plate of elliptical outline formed concavoconvex in cross section and mounted upon the pivot -J arranged above aportion of the top edge of the sleeve -j and preferably slightly belowthe upper extremity j of said upper edge.

As shown at Fig. 2, one extremity of the damper rests firmly against theinnerperiphcry of the pipe section d. at a point above the passage tothe branch pipe E, and the other extremity bears against the lower edge-f of the sleeve j, effectually and positively cutting oif the passageto the branch pipe E. On the con trary, when the damper J, as shown bydotted lines at Fig. 2, is swung into a horizontal position, itsupperend bears against the upper end of the inner sleeve -j and the oppositeend against the upper periphery of the pipe E-, thus positively shuttingoff the upward passage of the heated air or gas through the upperextremity of the pipe section d. This damper is extremely simple andeffective, and is readily operated by a chain J secured to the oppositeextremities of aleverJ mounted on the pivotal pin of said damper. Thechain J -is extended downwardly into close proximity with the top of thehood so as to be readily engaged by the attendant.

The upper extremity of the pipe D. may pass to any desired point, but Iprefer, as shown at Fig. 1, to mount thereon a suitable ventilator K,whereby, when nothing but heated air is passed through the pipe D, thedamper may be actuated to its vertical position, as shown at Fig. 2,thus preventing the passage through the branch pipe E., and permittingthe utilization of theair for heating an upper room. When, however,gases are generated and passed through the pipe -.D, the damper isactuated to its horizontal position and by the pipe E, the gases aredirected to the chimney instead of being allowed to contaminate theupper room, as would be the case weretheypermittedto pass upwardly andthrough the ventilator '-K The operation of myinvention will be readilyperceived from the foregoing description and upon reference to thedrawings, and it will be particularly noted that the same simple,durable and effective.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is

1. The combination with a chimney having an outlet passage, a stove anda stove-pipe for conducting the products of combustion from the stove tothe outlet passage of the chimney; of a hood mounted above the stove andmovable rectilinearly toward and away from the same and formed with acontracted elevated central portion, a telescoping ventilator pipeopening from said contracted portion of the hood for conducting theheated air and gases from the hood, and a branch pipe communicating withthe ventilator pipe and opening into the outlet passage of the chimneyat one side of the stove-pipe for discharging said heated air into thesaid chimney outlet passage independent of the stovepipe, substantiallyas described.
